Maximizing power from batteries to a DC Motor?

May 16Hits:1
Advertisement

I have this DC motor (the 38.2V version). I want to maximize the power put into it for 10-20 seconds, but I can only use 4 lithium 9V batteries. I know that as the batteries discharge, the voltage decreases.

From my research, I found some possibilities:

  1. Charge capacitors, which discharge into the motor.
  2. Use a Buck Converter, which would give me more current, but less voltage.
  3. Use a Boost Converter, which would give me the inverse of #2.
  4. Something else?

How would I do this?
